These couplings are capable of transmitting current up to a power of 1 A per contact. In addition, they have a vertical centralising effect. Thus, an unintentional stall (arriving at the bottom of a hill, for example), can be effectively avoided. Both a normal stall and an anticipated stall are possible. In this simple way, you can supply the entire train with the power needed to light up the interior of the carriages. Independent current collector brushes are not required on each wagon, which takes the strain off the locomotive (the traction forces required are minimal). The coupling is supplied complete with 2 connecting cables and can be inserted into an existing NEM 362 track.
